HOLDER FOR TANK-FLOATS.

SPEGLEICATION forming part of Letters Patent No. 754,965, dated March22, 1904.

i 7 Application filed .lpril 30, 1903- Serial No. 155,039. (No model.)

To on whom it may concern.-

' Be it known that I, GEORGE A. BLAKE, a citizen of the United States,residing at New Bedford, in the county of Bristol, State ofMassachusetts, have invented certain new and use: ful Improvements inHolders for Tank-Floats, of which the following is a specification.

The present invention relates to improvements in floats forball-cockssuch as are commonly employed in cisterns, flushing-tanks,&c.*and particularly to means for connecting such floats to the rod orarm by which the valve is moved.

The invention will be described in connection with the accompanyingdrawings, in which Figure 1 is a side elevation of a float having aholder embodying the present invention applied thereto. Fig. 2 is aperspective View of the holder shown in Fig. 1, the washer or plate forconnecting said holder to the valverod being removed and the floatindicated merely conventionally. Fig. 3 is a detail view, on an enlargedscale, of the said washer or plate. Fig. 4 is a perspective viewillustrating a slightly-modified form of holder; and Figs. 5 and 6 aredetail views of the washer or disk employed withthe holder shown in Fig.4, Fig. being a sectional view on the line 6 6 of Fig. 5.

Like numerals of referencedesignate corresponding parts in the severalfigures of the drawings, referring to which* 1 designates the float,which may be of any suitable size, form, and material, and 2 designatesthe rod or stem by which the float is connected with the ball-cock.

It is important that the float and stem or rod 2 be securely connectedand in such a manner that there is no danger of a leak being formed inthe body of the float by or at the point of connection thereof with thestem. By this invention the float is surrounded and securely held by acage or frame formed of a single wire and a disk or washer which isadapted to be attached to the valve rod or stem. The latter is providedon its outer face or surface with suitable grooves or recesses toreceive the members of the wire frame and with means for attachment tothe rod or stem 2.

The opposite lower face of the said dislror washer is made concave,being of such shape near its periphery as to conform to the exteriorsurface of the float 1, commonly made spherical in form, and is securelyclamped thereon by the wire forming the body of the frame or holder.

In the embodiment of the invention illustrated in Figs. 1 to 3 the saiddisk or washer 3 is provided with a centrally arrangedoutwardly-projecting stud 4, in which is formed an opening or passagethrough which the rod 2 extends, a set-screw 5 being employed to securethe said washer or disk to' the rod or stem. The said washer or disk isalso provided with four grooved arms 6, projecting radially from thesaid central stud 4, which is surrounded by a groove or waycommunicating with and connecting the inner ends of the grooves in saidarms.

The main body of the frame or holder is H formed by a single wire, whichengages the washer or disk 3 and binds the same firmly against thefloat. As shown in Figs. 1 to 3, the wire 7 extends completely aroundthe float and has its ends secured together, as indicated at 8. Saidwire is seated in the grooves in the arms 6 and in the connectingannular groove about the stud 4, so that the washer or disk 3 ispositively held from movement in any direction relative to the float.The said wire is also bent upon itself and has its end sectionsinterlocked at a point diametrically opposite the said disk or washer,as indicated at 9 in Fig. 1.

The form of holder indicated in Fig. 4 differs from that shown in Figs.1 and 2 only in the manner in which the wire forming the body of theholder is bent and engaged with the disk or washer by which itisattached to the valve-actuating stem or rod.,

In each case the said holder-frameis formed from a single wire7, bent toform a plurality of interlocked loops, each surrounding the float andfirmly engaging a washer or disk seated thereon, said loops beinginterlocked at a point diametrically opposite said plate or washer. Theform of the disk or washer 1O described and shown in Fig. 3. The washerhas only two grooves 11 formed therein on opposite sides of the centralstud 12, the arms 13 not being grooved, as in the washer 3. In the saidstud 12 is preferably formed a threaded socket in which a threadedextension 14: on the valve stem or rod 15 can be secured.

From the foregoing description and the drawings it will be seen that thepresent invention provides a very simple, strong, and inexpensive holderby which a float can be securely attached to the valve-actuating rod orstem.

The washer or disk by which the holder and float are attached to saidrod or stem may be made of various forms and the wire forming the bodyof the frame engaged therewith and with the float in any suitablemanner, the forms illustrated being those deemed most satisfactory atthis time.

Having thus described the invention, and without limiting myself to theexact details of the embodiments of the invention herein illustrated anddescribed what I claim, and desire to secure by Letters Patent, is

1. The combination with a valve-float, of a washer or disk seated on thefloat, a frame formed by a plurality of interlocked wire loops,surrounding the float and extending across said disk or washer toconnect it to the float, and means for connecting the washer or disk toa valve rod or stem.

2. The combination with a valve-float,of a holder or frame for saidfloat consisting of a single Wire bent to extend around the float indifferent intersecting planes, and means for connecting said holder orframe to a valve rod or stem. 7

3. The combination with a valve-float, of a 4 washer or disk seated onthe float and provided with grooves or notches, a frame formed by asingle wire surrounding the float on intersecting planes and securingthe disk or washer thereon by extending through the grooves or notchestherein, and means for connecting the washer or disk to a valve rod orstem.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. V

GEORGE A. BLAKE.
